SPECIFICATION formngpart of Letters Patent No. 295,997, dated April 1,1884. Application 4filed December '27, 1882. Renewed December 19, 1883.(No model.)

@ZZ w/"wm t may concern.-

Beit known that I, J. W. GILBERT, of Hoboken, in the countyof Marengoand State of Alabama, have invented certain new and useful Improvementsin Motors for Churns and other Light Machinery; and I do hereby declarethe following to be a full, clear, and eX- l act description oftheinvention, such as will i. .n enable others skilled in the artf to whichit l Io pertains to make and use it, reference being hadV totheaccompanying drawings, which form part of this' specification.

My invention relates to an improvement in i:` motors for churns andother light machinery; F5

and it consists, first, in the combination of a drum, a cord, wire, orchain, which is wrapped n around the drum in such a manner that whileone end is being wound upon the drum the other one is being reeled off,a grooved pulley,

and suitable weights which are to be attached n rst to one end ofthecord and then to the other,

With an operating mechanism which is connected to the drum for thepurpose of convertcomplete.

ing the rotary into a reciprocating motion; second, in the combination,with the operating mechanism, of a iiyy-wheel, and a checkspring whichis applied to the vertically-moving part, for the purpose of producing aregular and even motion, all of which will be more fully describedhereinafter.

Figure l is an edge view of my invention Figs. 2 and 3 are front andrear elevations ofthe upper portion of the same.

A represents a suitable frame, to which the `operating parts areattached, and which frame is 4supported upon the two legs C D, which maybe secured together and to the frame,

either in the manner here shown or in any 1 other that may be preferred.To the upper l 40 end of the frame is bolted the extension B,

y upon the upper end of which are placed suit- 1 able bars for the shaftwhich passes through the double-grooved pulley E. Secured dimade throughit,`so that the rod H can be` passed through; and the ends of the ropeare wound upon the drum in opposite directions, so that while one end isbeing wrapped upon the drum the other end is being reeled off. l

The cord may be passed through the drum, as shown in dotted lines, sothat the ends will wrap in opposite directions. The ends of the cord,wire, or chain H pass up over the double-grooved pulley E, and have eacha ring, S, secured thereto.

guide t, which is secured at its lower end to the extension B. Thisguide consists of a perforated plate, as in Fig. 3, and which is bent insuch a manner as to pass over the sides of the pulley and prevent theends ofthe cords from becoming displaced.

These cords are held in l i place uponV the pulley by means of the cord-Secured to the same shaft as the drum G is changed from one hole to theother, and thus cause a longer or shorter stroke to be given.

Secured to the frameF is the guide N, through which thevertically-reciprocating rod O -is made to pass, and this rod is twistedat or near its center, as shown, and just above the twist is secured theslotted plate Q, in which the wrist-pin catches for the purpose ofmoving the rod up and down. Also, secured to this slotted plate, andpassed up throughthe upper guide, M', is the rod R', upon which thecheck-spring S is placed. Upon the upper end of the rod R is placed asuitable regulating nut or nuts, by means of which the tension of thespring can be increased or diminished at will. As the lower end of thisspring S bears upon the guide M and as the rod R" is secured directly tothe vertically-reciprocating rod O, it will be nseen that at eachdownward movement of the rod O the spring serves to check the movementand to assist in raising the rod upward, and this spring, in connectionwith the :dy-wheel T, produces an even and regular motion.

Pivoted to the lower end of the frame A is the fan W, and this fan isconnected to the IOO coming displaced by the dasher-rod while inloperation.

In order to equalize the weight of the dasher, a Weight, W, is securedto one of the arms of the ily-wheel T in any suitable manner, and

f Which Weight may be adjusted back and forth upon the arm, for thepurposeof adjusting it to the Weight of the dasher. This Weight,counter-balancing the Weight of the dasher, serves to assist the Wheel Taround, and thus give a much more regular and even movement to the'different parts than can be done Where the dasher is left unbalanced. c

Vhen the churn is adjusted to the machine ready for use, a number ofWeights, proportionate to the amount of Work to be done, is

placed upon a hook, A, and then this hook is hung in the ring S, whichis attached to the end of the cord H', Which is raised highest from theHoor. These Weights cause the drum G to revolve and operate the churn orother light machine which is attached to the frame. When the Weightshave reached the floor, it is only necessary to detach the hook fromthat end of the cord and attach it to the other, when the machine willcontinue its motion. By this construction it Will be seen that there isno necessity for Winding any part up, for it is only necessary to changethe hook from one end of the cord H to the other end from time to time,as may be necessary.

I do not limit myself to any details of construction, as here shown, forthe parts may be bolted or secured together by means of setscrews, orany other Way that may be preferred.

.Having thus described my invention, I claim- V'1. In a motor, thecombination of the pulley, the cords passing over it, and a. perforated5o spring-holder, t, which catches over the pulley and preventsdisplacement of the cord, substantially as shown.

2. The combination ofthe reciprocating rod O, to which the churn-flasheris connected, with the slotted plate Q, the guide N, the rod R', andspring S, substantially as set forth.

3. The combination, in a motor for churns and other light machines, of aily-Wheel provided with a Weight upon one of its arms, the slottedplate, the rod O, the rod R, spring S', and guides N M, the parts beingcombined and arranged to operate as shown Aand described.

4. The combination ofthe vertically-m oving 65 rod O and a suitableguide with the fan W" and its connections U V and the dasher-rod,substantially as specied. V f

In testimony whereof I affix my signature in presence of tivo Witnesses.
